SASH-HOLDER.

SPECIFICATION forming part of Letters Patenty No. 250,828, dated December 13, 1881.

Application filed October 20, 1881.

To all whom it may concern:

Be it known that I, DAVID F. McKITEIox, of Marysville, in the county of Union and State of Ohio, have invented certainnew and useful Improvements in Sash-Holders; and l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference 1n arked thereon, which form part of this specification, in whichi Figure 1 is a side elevation, and Fig. 2 an edge View.

The object l have in view is to provide ay simple, cheap, and effective sash-lock, whereby the sash ot' a window may be quickly and securely locked either in a downward or upward movement; and to this end my invention consists in the peculiar construction and arrangement of devices hereinafter to be fully set forth.

To enable others skilled in the art to make and use my invention, I willv now describe its construction and operation.

A represents the sash to which the lock is attached, as shown in the dr-awings,and B the casing ofthe window-frame, against which the eccentrics press.

G represents the inner lock or eccentric, which is provided at or near its center with a suitable hole, and also with the stop or projection a.. This part of my device is cast solid from its outer end to a point a little beyond the pivot-hole, and from thence to the ange b'it is made somewhat less than half the thickness ofitsweighted end, as fully shown in Fig. 2. The ange b should be curved eccentrically to the pivot-hole, and its outer surface or rim is serrated, in order to give it a bite upon the casing.

D represents the auxiliary or supplemental eccentric, which is constructed or cast similarly to the one just described, except that it has no weighted end, and its hollowed side should be uppermost instead of downward, as is the case with the other. Its eccentric end should also be in a reverse direction, so that (Model.)

vent the sash from being raised until it is de sired to do so, when the heavy end may be thrown upward,thus relieving the easingfrom the bite of the eccentric.

c is the screw or pivot which contines the two parts together, and also to the sash, as seen in Fig. l.

It will be observed that the eccentrics O D maybe employed simultaneously-forinstance, the sash may be partially lifted and both ot' the eccentrics thrown against thecasing, which will prevent the sash from falling or being pushed upward'.

Having thus fully described my invention, what I desire to secure by Letters Patent isl. The combination, in a sash-lock, of the gravitating eccentric O, having projection or stop o, with the independent swinging eccentric D, the latter pivoted on top of the former, and both constructed and adapted to lock the sash singly or conjointly in opposite directions, substantially as set forth.

2. As a new article of manufacture, the within-described sash-lock, consisting of the gravitating eccentric G and the swinging eccentric D,the latter pivoted on top of the former, and both on acommon center, and adapted to operate as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

DAVID F. MCKITRICK.
